SHINGLE.

Specification of Letters Patent.

Patented Mar. 21, 1922.

To all whom it may ooncem:

lBe it known that I, NORMA): P. HARSH- BERGEB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have in'vented certain new.

as to present a very pleasing appearance and to prevent any leakage and at the same time to require a minimum amount of lapping. of the shingles, and hence to reduce to a minimum the amount of material necessarg to cover the roof.

f the drawings Fig. 1 is a plan view of a 'portion of a roof covered by my shingles; Flg. 2 is an under view of one strip of shingle material; Fig. 3 is a top view of another strip of material; Fig. 4 is an enlarged section along the line 4-4 of Fig. 3; Fig. 5 is another enlarged section along the line 5-5 of Fig. 2; Fig. 6 is aimaterially enlarged section along line 6-6 of Fig. 1; and Fig. 7 is a sectional view showing how the ends of similar strips are connected.

The shingles comprise a plurality of units connected m strips. While modifications ma be made in the number of units in a strip and in the Shape and dimensions of the units and strips, yet prefer the strips 10 and 11 composed of units 12 and 13 respectively. The strips 11, a plan view of which is shown in Fig. 3 are the lower strips, and have folded portions 111 spaced a material distance apart so as to form the unit portions 13, and when placed on the roof the edges 15 of the folded portions are placed upwardly and at the lower edgeof the unit and thus gives the a pearance of the ordi 'nary double butt shingle; and the strips,

ordinarily comprising 42 or 5 units, are connected together as indicated at the joint 16 of Fig..7 the arrang'ement being such that it is impossible for therain to work through at the joint. The strips 11 have cemented to their edges narrow strips 17 which prevent the rain working in over the edges of the strips. i

In laying the roof the-strips 11 are first placed upon the roof boards, suitabl spaced apart, and are neilfl to the moboards along the edges of the strips, for example,

at the points 18. The spaces-between the strips 11 are covered b the upper strips 10 which lap a material istance on the strips 11 at least sufliciently to somewhat more than cover the strips 17 The strips 10 also have folds 20 similar to thefolds 14, and at the ends may be connected similarly to the connection 16 of Fig. 7. Fig. 2 shows the underside of one of the strips 10, with blocks 21, of any suitable material, cemented to the lower side of the edges of the strips. These blocks have projecting fingers 22 which, when the strips 10 are placed on the roof, are slipped under the upper portion of the fold 14, Fig. 6., the blocks 21 coming on the strips 11 inside of the strips 17. Tu. this manner the strips 10 are held firmly to the roof by means of the strips 11, and it is necessary to nail down the strips 10ponly sufficiently to prevent them Afrom slding downwardly on the roof. These nailsmay be placed where convenient, for instance at the upper ends under the ridge strips.

Obviously the width of the strips 10 and 11 may be made whatever may be desired for appearance or use; the distance between' the folds- 14: or -20 may be var-led, and the amount of lapping of the strips may also be varied as much as desired, so as to vary the appearance or the amount of material used, or the amount of protection from weather, according to the desires of the builder.-

1 claim as my invention:

1. A roof covering comprising substantially parallel strips of roofing sheets fixed to the roof and spaced a material dis'tanee apart; other strips of roofing sheets placed on the roof covering the spaces between the first mentioned strips, and lapping thereon; all of the strips having transverse folds spaced a material distance apart, the folds in the first mentioned strips being aligned, but being staggered with the folds of the other strips which are also aligned; a narrow strip fixed to the upper side of each edge of each of the first mentioned strips; and blocks fixed to the lower side of each of the other strips, each of said blocks having a finger projecting upwardly and under the adjacent fold of one` of the first mentioned i strips.

2. roof covering comprising lower strips of roofing material running down the roof other, the strips in each and spaced a material distance apart, upper strips running down the roof between the lower strips and lapping thereon, each of the lower strips having a plurality of transall of the strips having transverse' folds spaced a material distance apart, the folds in the first mentioned stripsV being aligned, but being staggered with the folds of the other strips which are also aligned; and means fixed to the lower side of each of the otherstrips and passing under the adjacent fold of oneof the first mentioned strips.

4. A roof covering comprising two layers of strips of roofin material running down the roof, substantially parallel with each ayer being spaced apart, and the strips of the upper layer covering the spaces between the lower strips, each of the strips having transverse folds therein, the folds of the lower strips being alignedbut being staggered with the folds of the upper strips.

5. A roof covering, comprising-a plurality of laterally spacedrtop and bottom strips with the top strips extending over the spaces between the bottom stri s and overlapping the same along their si e/edges, each strip consisting of one continuous piece of roofing material, and being folded transversely upon itself at a plurality of spaced points in its length to provide a multiple thickness of material at each of such points to give the top surface of the strip a step-shaped appearance; the folds 'in the bottom stri s bemg out of alignment with the foldspm the top strips to givethe roof covering a shin- ``gled appearance'.

6. A roof covering, comprising a plurality of laterally spaced top and bottom stripsv with the top strips extending over the spaces between the bottom strips and overlapping the same along their side edges, each strip consisting of one continuous piece of roofing material, and being folded transversely upon itself at a plurality of spaced points in1 its length to provide a multiple thickness of material at each of such points to give the top surface of the strip a step-shaped appearance; the folds in .the bottom strips being. out of alignment with the folds in the -op strips to give the roof covering a shingled appearance, and means carried by the top strips on the under sides thereof to engage in the folds in the bottom strips for holding the strips togetherj p 7. An article of manufacture comprising a strip of sheet roofing adapted to be laid transversely on a roof and having a plurality of equally spaced transverse closed double folds, one end of each of said strips having a transverse single fold adapted to coact withl a similar fold of another strip so as to increase the effective length of the strips, and narrow strips fixed to each longitudinal edgeof each of said strips.

8. A roof covering, comprising two layers of strips of roofing material running down the roof, the strips in each layer being spaced apart a material -distance and the strips of the upper layer covering the spaces between the lower strips, each of the strips having transversedouble folds, the folds in the respective layers being aligned, but being staggered wlth the folds of the'strips of the other layer, and a strip of material fixed to the upper side of each edge of each ofthe lower strips and extending the entire length of said strip.

lI-n testimony whereof, I hereunto set my hand.
